Specifications obtained under laboratory conditions of gas flow, temperature and humidity. Field performance is
dependent on the correct installation procedures been followed, environmental conditions, frequent sensor cleaning and
regular calibration. Some of the sensors have cross sensitivity, for more information contact Ionscience.
